NEW YORK, N. Y., ASSIGNORS, BY DIRECT AND MESNE ASSIGNMENTS, TO FRANK-LIN RAILWAY SUPPLY COMPANY. OF IWILMINGTON. DELA\VARE. A CORPORATION OFDELAIHAIREQ This invention relates to flexible pipe couplings, and more.particularly to such pipe joints or couplings for connecting the ipesections on the engine and tender of a ocomotive or other vehicles of atrain. Pipe connections of this character for conducting water, steam,or other fluid from one vehicle to another must have sufiicicntflexibility to provide for the relative movement between said vehiclesin the'running of the train, and the principal object of our .invention'is to providcan improved conpling of this type which shall be of simpleand compact construction and having a longitudinally slidablc membermounted on one of the vehicles for allowing for the slack movementbetween the same. 7

In the accompanying drawings: Figure 1 is a side elevation of a pipecoupling em bodying our improvement, and applied to the water conductingpipe from a tender to an engine of a locomotive; Fig. 2, a side -,-view,partly in longitudinal section, of the improved coupling device adaptedto be mounted on the engine; and- Fig. 3, an end view of the same.

According to our improvement, one of the vehicles, preferably'theengine, is provided with a bracket, 5, preferably secured just beneathand substantially in the same vertical plane with the draw bar, 6, andhaving! a tubular member, 7, in which a telescoping pipe section, 8, ismounted to slide. A peeklng nut or gland, 9, is mounted on the Ullllkla'r member, 7, and around the pipe, 8, to prevent leakage at thesliding joint. The pipe, 8, is connected to the body, 10, o a universalcoupling, preferably a ball and socket joint, the other member, 11. ofwhich is connected to the pipe, 12, extending to a similar coupling, 13,on the other vehicle. In order to assist in the guiding and supportingof the body, 10,"of the ball joint, an

extrusion guide. 14. may be 1u'ovided proecting longitudinally, andslidably inountcd in an arm. 15, of the bracket. For-the purpose ofreadily uncoupling lhe'engine and tender, the pipe, 12, is providedwit-h a flangeiunion, l6.

The tubular portion, ,7, may be connected by means of a suitable union,'17, with a fitting, 19, having one or more branches for connecting withcorresponding pipes carried on the engine, and in a similar manner, thebody portion of the coupling, .13, on the tender ma y be connected toone orlmore pipe lines. \Vhere the coupling is used for conductingwate'r, the branches on the tender 'may lead from the tankv-valves, andthe -l"atc.i|te(l Dec. 1, 1914.

branches on the engine be connected to two It will now be seen that theuniversal or ball joints, 10 and 13, provide for all of relative lateralswinging a'nd vertical movements between the respective vehicles, whilethe longitudinally sliding joint allows'for all of the relative slackmovement. As the referably located beneath Or in line with t e draw bar,the relative movement to be accommodated is thus reduced to a minimum.

Having now described our invention, what we. claim as new and desire tosecure by Letters Patent is:

1. In a pipe coupling for railway vehicles, the combination of a tubularmember supported on one vehicle, a telesco ing section mounted to have arelative ongitudinal sliding movement therewith, a longitudinal guidefor said telescoping member, and a pipe section having a flexible jointcommunicatin with said telescoping member.

2. In a pipe coupling for railway vehicles, the combination of a drawbar, a tubular member supported on one of the vehicles substantiallybeneath and in vertical plane with said draw bar, a telescoping pipesecthe combination of a tubular member supported on one vehicle, atelescopin pipe section mounted to have a longitu inally slidingmovement relative thereto, a universal joint communicating with saidtelescoping section, another universal joint member connected to thepipe line of the other vehicle, and a pipe section having a detachableunion connecting said universal joint members. i

4. In a pipe coupling for railway vehicles, the combination of a brackethaving a tubular member adapted to be supported on one vehicle, atelescoping section mounted to have a relative longitudinal slidingmove- I ment therewith, a projecting guide extending inline with saidtelescoping member, a bearing for said guide, and a pipe section havinga flexible joint communicating with said telescoping member.

5. In a pipe coupling for railway vehicles, the combination with a.bracket adapted to be supported on a vehicle and having a .tubularsection and a guide bearing, of a universal coupling having a bodyportion provided with a telescoping section extending within the tubularsection and mounted to slide longitudinally, and a guide projectin inthe opposite direction through said guide bearing of the bracket.
